BIOGRAPHICAL SUMMARY

William J. Riley is a scientist in the Climate and Carbon Sciences Program at Lawrence Berkeley National Laboratory. Dr. Riley is a biogeochemist who studies the natural and anthropogenic carbon and nitrogen cycles, coupled land-surface and atmosphere exchange, and climate change. His work involves using numerical modeling to elucidate mechanisms relevant to ecosystem function, exchanges with the atmosphere, and their interactions and feedbacks. He has published work on land-surface atmosphere feedbacks, the use of isotopes (e.g., 14C, 18O, 15N) as ecosystem tracers, distributed modeling of heterogeneous landscapes, coupled carbon and nitrogen cycling, and fossil-fuel and ecosystem CO2 transport in the atmosphere.

RESEARCH INTERESTS

Interactions between the soil, biosphere, and atmosphere that impact carbon and nutrient cycling, hydrological flows, leaching, and trace-gas fluxes important in climate change; environmental fluid mechanics and the interactions between fluid flows and biological processes that affect environmental quality; numerical modeling of coupled hydrological, biological, and atmospheric systems; use of carbon and oxygen isotopes in coupled hydrological and biological systems; and impacts of intensive agriculture.

PROFESSIONAL EXPERIENCE

Scientist, Lawrence Berkeley National Laboratory. 2000 through present. My current work focuses on the development and testing of mechanistic models of coupled physical, biological, chemical, and atmospheric processes important in predicting mass (e.g., H2O, CO2, NO, and N2O) and energy balances at the earth’s surface.
